forward.
Ground cable
NOTE:
For AC-powered switches, although the third conductor of the AC power cord provides a ground path, Dell EMC
recommends grounding your switch with a dedicated ground wire.
NOTE:
For DC-powered switches, the only way to safely ground your switch is to attach a dedicated ground wire.
Depending on the type of switch, to attach a ground cable to the switch, you need M3 or M4 screws.
The switch ships with one of the following two configurations:
•
One threaded hole using an M3 screw.
•
Two threaded holes using one of the two M4 screws.
In both configurations, the ground cable is not included. To properly ground the switch, Dell EMC recommends a one- or two-hole lug, M3
or M4 hole size. The ground lugs must be a UL-recognized, crimp-type lug.
CAUTION:
Grounding conductors
must be made of copper. Do not use aluminum conductors.
